Given the option to buy a Mustang, you can select either the V6 engine, or the baddass, tunable, upgradable, historic, legendary and emotional V8... Now, here's the reasoning:::

You only buy the V6 Mustang because of:
A- Your budget only allows the V6
B- You're the biggest imbecile in the face of our planet Earth.

So, if reason A isn't a problem, it's pretty obvious how many cylinders you'll end up with.

The more the better...

1000W vs 600W... 1000W wins
Now....
1000W vs TWO 600W.... the twins win
